5894 Milliohmmeter with micro-ohm resolution.

The 5894 Milliohmmeter is suitable for applications that require either a milliohmmeter or micro-ohmmeter.
The robust design is suitable for workshop or laboratory use. It has an impressive range of features included as standard.
Two measurement modes are available: “Fast” for normal resistance and automated processes and “Slow” for the accurate measurement of inductive devices such as motor and transformer windings.

Milliohmmeter

Model  Description 
5894  5894 Milliohmmeter. High resolution ohmmeter.

Measuring range 1.0000mOhms to 100kOhms
Maximum resolution 0.1microOhm
Accuracy 0.03%
Current setting from 10 microA to 1A
Measuring Voltage 4V
Printer Interface, PLC Interface
Programmable Limits
RS232C port for full external control of the instrument

The Milliohmmeter is also provided with an input protection circuit to guard against voltage spikes that can occur when measuring inductive components.
By simply connecting a resistance thermometer, measurements of copper and aluminum can be made
relative to 20°C.
A special feature to limit the open circuit voltage to less than 20mV is included to enable “Dry contact
resistance” measurements to be made.
